Definitions
- This invention relates to a liquid composition for defoliation of crop plants. More particularly, it relates to a liquid composition for defoliation of crop plants and a 3 ⁇ 4 process of preparing said composition.
- a defoliant is a substance which when applied to a growing plant, which is normally i3 ⁇ 4 undergoing defoliation during its life cycle at maturity, causes an accelerated dropping of the leaves without destroying the plant
- defoliants must be effective in relatively low concentrations.
- Defoliants are generally applied to crop plants when crop is about to reach the harvesting stage. Defoliants are applied either as solid formulations (e.g. dust or powder, granules) or liquid formulations (e.g. S uspension concentrate, E mulsifiable concentrate etc).
- the problem with the solid formulation is dustabiiity, 3 ⁇ 4 low pourability, difficulty in packing, health hazards due to inhalation and skin irritation.
- Dust defoliants are bulky, difficult to apply uniformly, dependent on dew for retention and activation on the cotton plant, and highly susceptible to drift. Also, it is difficult to make available the effective amount of active ingredients onto the foliar parts in the presence of wind and other ecological factors. Liquid formulations
- 3a can be prepared conveniently even at the time of application by mixing a dispersible powder, solution, or suspension of defoliant chemical with water. Liquid defoliants along with surface active agents when applied to plants, they spread on the leaves rather than gathering into drops, thus providing a much larger area of contact and, in addition, tending to ensure that the defoliant will remain on the
- products such as pentachlorophenol, sodium chlorate, magnesium chlorate, magnesium chlorate hexahydrate, calcium cyanamide, sodium 3, 6-endoxohexahydrophthalate, etc.
- the chemicals are available as either dusts or sprays and can be applied, by either airplanes or ground machines with one exception ' if it is necessary to defoliate only the bottom part of a plant at a given time, only ground machines and sprays can be used.
- Magnesium chlorate is a known defoliantsince long. This chemical was first offered commercially for use as a cotton defoliant in 1952. C urrently it is available as magnesium chlorate hexahydrate and as magnesium chloride-sodium chlorate, which are mixed together in aqueous solution, to form magnesium chlorate hexahydrate. Magnesium chlorate is an effective defoliant and is preferred where til foliage is tough and more leaf surface activity is required. Magnesium chlorate is applied in the form of solid powder as well as liquid spray defoliants. It is observed that the better defoliation is obtained when plants are treated with a liquid spray of Magnesium chlorate.
- the present invention seeks to overcome at least one, and preferably more than one, of the above disadvantages.
- a liquid composition for defoliation of crop plants comprising:
- a process for preparing a liquid composition for defoliation of crop plants comprising:
- a method of defoliating crop plants comprising applying, to the crop plants that are required to be defoliated, a liquid composition comprising a metal 3 ⁇ 4 chlorate; and a reduced quantity of an alkali metal halide.
- the present invention provides a liquid composition for defoliation of crop plants, the composition comprising:
- i3 ⁇ 4 (b) a reduced quantity of an alkali metal halide. It has now been found that a defoliant composition containing a metal chlorate as the defoliant is more physico-chemically stable and demonstrates better defoliant and burndown activity when the quantity of the metal halide in the composition is reduced in comparison to the conventional defoliant compositions. All the 3 ⁇ 4 conventional defoliant compositions included an appreciable quantity of the contaminant , alkali metal halide. It was found that when liquid defoliant compositions were prepared comprising reduced quantities of the alkali metal halide in comparison to the conventional defoliant compositions, the resultant compositions surprisingly possessed better physicochemical stability in addition to 3a improved defoliant and burndown activity.
- reduced quantity_of alkali metal halide denotes a quantity of the alkali metal halide that is less than 30% by total weight of the composition, preferably less than 20% by total weight of the composition, more preferably less than 10% of weight of the composition, and most preferably less than 7.5% by total 3 ⁇ 4 weight of the composition.
- the liquid composition for defoliation of crop plants comprises from about 0.1 % to about 95% and preferably from about 10% to about 80% of the metal chlorate by total weight of the composition.
- the metal chlorate is present in an amount from about 20% to about 70% of the total weight of the defoliant composition.
- the metal chlorate defoliant may be selected from the group consisting of sodium chlorate, magnesium chlorate, calcium chlorate, calcium- magnesium chlorate and potassium chlorate.
- the metal chlorate defoliant is magnesium chlorate. In an embodiment, the metal chlorate defoliant may include trace amounts of inherent phosphorus.
- the defoliant composition of the present invention comprises a 3 ⁇ 4 reduced quantity of an alkali metal halide than is present in all known defoliant compositions.
- the defoliant composition of the present invention comprises a reduced quantity of sodium halide.
- the defoliant composition of the present invention comprises a reduced quantity of sodium chloride.
- the liquid composition 3 ⁇ 4 for defoliation of crop plants comprises from about 0.1 % to about 30% and preferably from about 1 % to about 20% of sodium chloride by the total weight of the composition.
- sodium chloride is present in , an amount from about 2% to about 10% of the total weight of the herbicide formulation.
- the defoliant composition of the present invention comprises water.
- water is used in a sufficient quantity to enable stable compositions of the metal chlorate defoliant of a desired strength to be prepared.
- the percentage quantity of water present in the liquid compositions of the present inventions is not particularly limiting and may be conveniently decided by a person t3 ⁇ 4a skilled in the art.
- the liquid composition of the present invention is in the form of an aqueous formulation.
- the aqueous formulation of the invention has greater ease of application in defoliant actions, greater ease of application in burndown actions, can be used to defoliate crop plants even in relatively cool weather, has a 3 ⁇ 4 normal spraying moment without any drift and therefore does not cause any harm to the neighbouring crops, and does not produce foam during application of the composition on the crop plants.
- the present invention provides a process for preparing a liquid 3a composition for defoliation of crop plants.
- the process for preparing the liquid composition comprises:
- the alkali metal chlorate and alkali metal halide form the cation portion of the metal halide component of the composition, while the second metal halide provides the metal portion of the final metal chlorate defoliant .
- sodium chlorate and sodium chloride are dissolved in water, to which an alkaline earth halide is added to form the corresponding alkaline earth chlorate defoliant
- sodium chlorate and sodium chloride are dissolved in water, to i3 ⁇ 4 which magnesium chloride is added to form the corresponding magnesium chlorate defoliant.
- This composition comprises sodium chloride as the salt
- the liquid composition remains stable at low temperature.
- the defoliant composition of the present invention may be ⁇ 3a prepared by a non-limiting process comprising the steps of: (a) dissolving sodium chlorate and sodium chloride in charged water at temperature not exceeding 40°C in a suitable assembly;
- the present invention also provides a method of defoliating crop plants, said method comprising applying, to the crop plants that are required to be defoliated, a liquid composition comprising a metal chlorate; and a reduced , quantity of an alkali metal halide.
- the liquid composition is effective in defoliating crop plants even at relatively cool weather.
- Liquid compositions (Table 3) were prepared according to the process disclosed in the present invention with 5% and 10% sodium chloride respectively.
- liquid composition (Aq1 , Aq2 and Aq3) were prepared at different dosages of magnesium chlorate (3Kg/Ha, 4Kg/Ha and 5Kg/Ha) to optimize effective dose of magnesium chlorate in the liquid composition as burndown.
- S olid ⁇ 3a composition (S I1 , S I2, S I3 and S I4) were prepared with varied dosages (3Kg/Ha, 4Kg/Ha and 5Kg/Ha) of magnesium chlorate. All these compositions were evaluated for burndown activity. T he bean crop was evaluated on second day after treatment for defoliation action of liquid composition (Table 6 and F ig. 2). C rop received three treatments with different dosages vis.
- liquid composition having lesser sodium salt i3 ⁇ 4 content of the present invention showed far more superior effect in both defoliation action as well as burndown action.
- the liquid composition with lesser sodium salt content does not affect the plant adversely.
- the liquid composition is found better than the solid conventional composition of Magnesium chlorate in terms of efficacy.
